The Solenoid Electromagnet

Optimization of the Shape of an Electromagnet: Regularity

In this paper we study the regularity of the solution of an elliptic partial di erential equation with discontinuous coe cients. This result is used to establish the continuous Fr echet di erentiability of a shape functional arising in the optimal shape design of an electromagnet.

The Compact Muon Solenoid Experiment

Optical transmission characteristics of multi-mode synthetic silica-core bers between 325 nm and 800 nm were studied in situ while irradiated with neutrons. In one case, ber samples were placed near the core of a 10-kWatt reactor; in the other, fast neutrons generated by p(18 MeV) + Be reaction in a cyclotron, irradiated the bers. The neutron uence in both studies totaled 10 15 n=cm 2. Both of ...

The Compact Muon Solenoid Experiment

Relativistic heavy ion beams are an intense source of (quasireal) photons with a spectrum extending up to several hundred GeV, due to the high charge Z and the large energy of the ions. In this note we discuss the possibility of using this in peripheral collisions for photon-photon physics. We discuss the total luminosities that can be achieved with diierent ion species. In order to suppress ce...

2 Parameters of the Bent Solenoid Channel

Using the analytic estimates developed for the emittance diagnostic channel for the nal-stage cooling experiment, we conclude that diagnostics for both an initial-stage cooling experiment, and for the targetry experiment could be performed with a bent solenoid of 1.25 T eld strength. The solenoid bore would need to be at least 40 cm for either study. The targetry study is less demanding in accu...
